Abstract
A filter for removing undesired materials from a fluid, such as used cooking oil, for example, includes a filter envelope including first and second panels. The first panel has a permeability which is greater than that of the second panel. The first panel of the filter envelope may be formed from a filter pad and the second panel from a filter paper, and may enclose a metal spacer grid. When the filter is connected to a pump for drawing the oil through the filter, the flow of the oil is directed selectively through the filter pad, whereby undesired materials are removed from the oil. The filter provides for efficient flow of the oil to be filtered while removing undesired materials therefrom.
